Application filed Februaryli, 1924. Serial No. 692,306. I
My invention relates to improvements in sharpeners for edge tools, implements, and
, skates. it. is ideally adapted for sharpening skates since it produces a-hollow ground edge, which is highly desirable, and which is not readily obtained by a file, or any device using a file.
In its preferred form, my sharpener comthe skates from the feet, draw the runnerof each skate over the cutters.
In the drawing- Figure 1 is a transverse sectional view of the sharpener on line 1-1 of Fig. 2;
Figure 2 is a longitudinal sectional view on line 2+2 of Fig. 3;
Figure 3 is an end View of the sharpener in sharpening position on a skate;
Figure at is an end'view with one guide r moved and the other guide arranged in a position adapted to sharpen bevel edges on tools etc.
Figure 5 is a front view of one of the guide members;
Figure 6 is a fragmental View similar to Fig. 2, of a modified form without the separating washers;
Figure 7 is a fragmental View similar to Fig. 2, of a modified form with plain discs having no projections, and with separating washers;
Figure 8 is a view showing the manner in which the cutter discs tilt to sharpening position when a skate is drawn over them in the direction of the arrow;
Figure 9 is a front view of one of the sharpening discs shown in Fig. 2; and 45 Figure 10 is a section of Fig. 9on line My sharpener preferably comprises a housing or main body J soshaped that the sides K almost enclose the cutter or sharp ener discs 6, thus protecting the hand when using as shown in Fig. 3. The top of the housing is formed into a foot L with a hole m ateach end for attachment in permanent position, when so desired. Mounted in the ends 0 of the housing, is a shaft or pin 03 carrying a plurality of sharpening discs I) separated by. spacing or, separating washers c. The cutters and washers have free spaces a. between them to allowforthe change of position shown in Fig. 8. The holes 7) in the cutters and washers-are much larger than the shaft d as shown in Fig. l to per- [hit the cutters to assume the slanting or H tilted position of Fig. 8.
lVhen used for sharpening skates, (Fig.
3) guide members e are secured to ends 0' by screws 9 passing through slots f, thus providing a guide space or slot A, which can be made of suitable width to accommodate the exact thickness of any blade, by sliding the guide members laterally to each other on screws 9 and securing inthe desired ad justment by tightening said-screws g.
iVhen used for sharpening bevel edges on tools, etc., one guide e is removed from each end 0 of the housing and the remaining guides are tilted, and secured in any desired position (Fig. 4) by screws 9 at each end. Thus at each adjustment of guides e, thre'e angles h are provided for sharpening purposes.
When plain sharpening discs 9 are used as shown in Fig. 7 it is desirable to separate them with washers 0. But when sharpening discs with projections orpressed out por tions 1' are used, washers may be used as in Fig. 2 or they may be dispensed with as: in Fig. 6 since the projections r act to keep the main body port-ions of the sharpening discs spaced from each other. Another advantags of these pressedout projections is that when the discs are piled together to carbonize them, the projections keep the edge portions of the discs separated from each other and permit the entire edge portions to be come carbonized. Thus when hardened, the cutting edges will be hard all over, and therefore free from soft spots.
I claim:
l. A sharpener comprising a support, a single row only. of axiallyarrangedsharpening dis-cs tiltably mounted on said sup port, and non-sharpening guide means in cooperative relation with said discs.
2. A sharpener comprising a support, a single row only of axially arranged sharpening discs tiltably mounted on said support, and adjustable guide means on said support.
i 3. A sharpener comprising asupport, a
plurality of sharpening discs. tilta-bly mount-I ed on said support, and guide means on said support adjustable to provide a. slot of Various Widths.
4. A sharpener comprising a. support, a plurality of sharpening discs mounted on said support, and guide means on each end of said support adjustable to provide a slot of various Widths.
5. A sharpener comprising a support, a plurality of sharpening discs mounted on said support and guide means on said support con'iprising a plurality of members adjustable relatively to eachoilher to provide a slotof various Widths, one or more of said members having aislot inan edge spaced from said adjustable. slot.
6. A sharpener comprising a support, a
plurality of sharpening d-ises mounted on said support; and washersamounted; 0112- said support between the sharpening discs, said discs having lateral. projections. v
7; Asharpenercomprising aisupport', axially arranged sharpening disks tiltably mounted on the. support, and means mounted in proximity to the disks and adapted to be swung intopositionnfor guiding a tool over the edges of the disks.
8. A: sharpener coni'p irising a: support; aX
ially arranged sharpening; disks L tiitab ly mounted on x the: support; 7 andi as. guide :1 lug.
n iounied in. proximity tosand extending be yond the disks,- adapted-Re ben swung int-o. position for guiding aitoolpver thevedgesi oi the disks.
